What tools do you recommend for hacking?

Question

C++ / C#

Good afternoon.
I want to test my library, written on the pluses, for the complexity of hacking.
What tools and articles do you recommend?
Preferably with a low threshold of entry - in order to take a look at the possibilities of hacking the library with one eye.
Thank you.

Answer 1

What exactly to break in the library? Do you have any protection?
Tool - normal : www.idapro.ru

Answer 2

YOU(!) will not be able to test your library for hacking difficulty. It has to be done by someone other than you.
